. horizontal section of the paddle wheel, Fig.

3. horizontal section of self cleaning carrier.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my machine by using two base pieces, four by six inches, fourteen feet longshown by W, I use three cross pieces,

one at each end, the one at the hind end' bolted under W, forming the axle for the hind wagon wheels the middle one crossing under front of thresher, shown by Fig. 3; my machine is made three feet in the clear inside; except thresher is two feet ten inches the length of cylinder; thresher legs or posts, three feet ten inches high four by four inches square, four side girths, three feet, shown by Fig. 2 on thresher; the top of cylinder girths eleven inches from top of `posts to top of girths to be four inches square, the lower ones 3 by 4 inches, shown by Fig. 2, to be framed eighteen inches from the bottom of posts, the object of the lower ones being 3 by 4 is to have it outside of roundhouse or windmill; the side to be filled between girths with a panel one inch and ahalf thick, to receive bed or concave to cylinder; I use three cross girths, the two across front posts, over Fig. 3 shown by dots back from posts, the bott-om one eight inches from bottom of posts, upper one four inches above cylinder girths; the one across back posts next to carrier, to cross four inches below lower side girths or Fig. 2, the

top of back posts to be capped across the cap to be two by four inches square; cylinder A to be made fourteen inches in diameter; to be made in thefollowing manner. Take two thicknesses of solid wood, two inch plank for each head crossing the grain of the wood, pinor screw them together; cut gains three inches on the surface or out- .side as shown at a three inches deep by two inches atI the bottom; the side of beaters the heads to be placed in three inches from end of beaters, after beaters are fitted and pinned into heads banded with or 4 inch band iron, to be fastened on an iron shaft one inch and half square the cylinder beaters covered with sheet iron to be spiked with half inch round rods, one and three fourths of an inch out from the beaters and concave, the concave vl0 inches wide by 3 in. thick slides in with half in. gore covered with sheet iron spiked with 5 half rows of spikes as described above. To clear three sixteenths of an inch in the mesh, to have a collar'on each end of shaft on the inside of each bearing or journal, which. is two feet ten inches apart or in the clear, the journal to be long enough to receive a pulley six inches long on each end; the supporting posts is shown at V two feet six inches long four by four inches square, framed at the bottom to W a cross piece tive inches from the top 2 by 3 inches square shown by Fig. 3', a short tenon on the top of posts for carrier to drop `onone inch long, all the short posts under bottom rail of carrier as shown by Y are to have tenons of one inch long for the purpose of taking carrier olf at pleasure; the posts next to thresher that has pulley block, as shown by C is framed in loop at the bottom to be tied or hooked -at the bottom; these posts are to be three feet ten inches long, two and a half by three inches square; the bottom rail of carrier shown by Y frames is fifteen inches up from the base shown by l/V, the top rail of the same seventeen inches up from the bottom, one inch and a half by two-length of bottom rail to lst carrier is 4 feet long, shown by Y is seven feet; the posts of thresher and carrier is eight inches apart in order for chain to open to clear itself and to tighten endless chain O. Pulley shown at C is ten inches in diameter is made of two inch plank bolted on with a half inch bolt with a smooth fiat head on the inside pulley block or tightener which may be done by a key block or screw; is ten inches up from rail Y in order to give the drop or hinge room to open that all straw and grain that falls through from top of carrier inside of carrier may escape; upper pulleys in first carrier shown at F is made of two inch plank eight inches in diameter with collar or gear on the outside of the pulleys made by putting on a half inch board of bass wood or elm brought down o-n the edge to one fourth of an inch to project out half inch to serve as a guide to prevent chain from rubbing sides of carrier, these pullies to be hung on shafts or axles three fourths of an inch square to run across carrier and extend out at each side three inches to receive pulleys on each end outside of carrier; the paddle wheel shown at G between carriers is for the purpose of paddling back what grain drops through second carrier under first carrier chain where it is drawn back and falls on shoe of cleaners sho-wn at X the paddle wheel Gr made of three inch plank siX inches wide or any convenient size brought down to a half inch on each edge with a half inch gudgeon A eachend thev one leftV hand side marked a (Fig. 2) to be long enough to receive a pulley.
